OIL--SEPARATOR.

. A lication filed July 7, 1917. Serial No. 179,194.

2"?) all whom it may concern Be it known that we, BENJAMIN G. Conn" MAN and Roma U. MORRISON, citizens of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Oil-Separators, of which the following is a specification. This invention relates to separators especially designed for separating oil from water, after it has passed from the engine exhaufpt, in order that the said oil may be again use The primary object of the invention is to provide a device positioned to receive the oil from the engine exhaust, in which the oil is treated to effect a separation therefrom of water and scale, inorder that the oil may be restored to its former condition to be again used for lubricating or other purposes, the heat of the oil being retained, so that it will remain warm and ready for use.

Withthe above and other objects in view, the invention consists of the following novel combination and arrangement of parts. hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the claims hereto appended.

In the drawings,

Figure 1 is a vertical sectional view of a separator embodying the present invention;

Fig. 2 is a detailed elevation showing a part of the separator casing and the slide for adjusting the water outlet to control the water level; and

Fig. 3 is a similar view showing the draw off cock of the oil chamber.

Fig. 4: is a sectional view on the line 4% of Fig. 1. Fig. 5 is a detailed view of the oil discharge pipe. Fig; 6 is a detail sectional view of the check valve.

Referring to the drawings in detail, there is illustrated a receptacle comprising a casing 10, which'is divided into an oil receiving compartment or chamber 11 and a water chamber 12, the division being made by means of a partition 13.

The oil receiving chamber is adapted to receive the used oil, which passes from the exhaust 14,- from where it is conveyed by means of the pipe 16 into the. receiving chamber 11.

The receptacle 10 also has included therein an oil chamber 17, which is adapted to receive the oil after it has been separated from the water, scale and other extraneous matter.

The partition 13 terminates short of the bottom of the oil chamber '17, which latter chamber is located within the upper portion of the receptacle 10, the space between the upper end of the partition 13 and the bottom of the chamber 17 providing a passage 18. The water chamber 12 is divided by means of a partition 19, which forms an extension in the end of the oil chamber 17, the said partition terminating short of the bottom of the water chamber to provide a passage 20, by means of which communication is established from each side of the partition 19. The water chamber 12 is provided with an outlet in the "form of an adjustable pipe 21, which is carried by a slide 22 suitahiy secured to the receptacle 10, the said slide Toe-- ing capable of vertical adjustment for the purpose of regulating the level of the water within the clnfmbcr and receptacle. This manner of arranging the water chamber pro.- vides in effect a passage. through which the water passes to enter the passage 24, thereby retarding its progress to the outlet pipe 21.

The pipe 16 is open at its bottom end, which end terminates short within this chamber above the bottom of the pipe is a horizontal partition, approximately one-half of which is provided with perforations, while the other half is solid, the latter portion forming a retarding diaphragm 25,

while the perforated portion provides a filtering screen 26.

Oil and water from the pipe 16 enters the bottom of the receiving chamber below this partition; the diaphragm 25 retarding the upward movement of the water and oil, causing it to seek an outlet through the 511- tering screen 26, which holds the scale and sediment below said screen and permitsit to settle to the bottom of the chamber.

Located within the oil chamber 17 is an oil discharge pipe 27, one end of which is secured within an opening 28 and communicatcs with the receiving chamber 11. The pipe 27 is provided with aseries of openings 29, and located below this pipe and in position to receive the oil therefrom is a filtering pan 30, so that the oil which may'enter the chamber 17 from the chamber 11' passes through the filter 30, all the impurities being taken therefrom and the oil restored to its original condition. As the pipe27 is located above the outlet pipe 21, the water is prevented from entering the pipe 27, the

' Patented Nov. 3252, 1933,

of the bottom' of the receiving chamber 11 and positioned positioning of the pipe 21 establishing the Water level.

An outlet pipe all communicates with the chambers 11 and 12, so that the said chamhere may be emptied at any time, the pipe 32 extending from the pipe 31 in position to receive the waste Water in the last men-' tioned pipe. The end 36 of the pipe 31 opens into the chamber 11 While communication with the chamber 12 is established through the medium of a check valve 37, of the ball type as shown in Fig. 6, so that communication between the chambers 11 and 13 through the pipe 31 ,will be pre vented. A. valve 38 located in the pipe 31 provides for draining the chambers 11 and 1'2. i

Sight gages 33 and 3d are provided respectively for the chambers 11 and 17, the last mentioned chamber being also provided with a draw olf cock 35.

It is believed that from the foregoing de scription when taken in connection with the accompanying drawings, the construction, operation and advantages ofithe invention will be apparent. .'The right is reserved to make such changes in the form and proportion of the invention as will fall Within the scope of the claims hereto appended. v Having described the invention, what is claimed is;

1. An oil separator embodying a receptacle including a receiving chamber, a Water chamber located Within the receptacle and communicating with the receiving chamber near the top of the receptacle, a supply pipe extending into the receiving chamber and having an outlet near the bottom of the receiving chamber, a combined retarding and filtering screen located in said receiving chamber above said outlet in the path of the contents of the supply pipe, an adjustable outlet for regulating the level of the Water in the receptacle and an oil outlet located within the receptacle above the Water outlet.

2. An oil separator embodying a receptacle, a supply pipe therefor, said pipe communicating with the receptacle at a point near the bottom of the latter, a vertically disposed'partition dividing the receptacle into a receiving chamber and a Water chamber, said partition terminating short of the top of the receptacle to provide a communication passage between the chambers, a sec-.

0nd partition dividing the Water chamber, said second partition terminating short of the bottom of said chamber, a retarding and filtering screen located Within the receiving chamber above the supply pipe outlet an oil chamber located in the top of the receptacle and in communication with the receiving chamber and a Water outlet for the Water chamber located below the point of communication of the oil chamber With the receiving chamber.

In testimony whereof We aifix our signa tures.
